The Environments of Luminous Radio - WISE Selected Infrared Galaxies
J. I. Penney, A. W. Blain, D. Wylezalek +17
We have observed the environments of a population of 33 heavily dust obscured, ultra-luminous, high-redshift galaxies, selected using WISE and NVSS at 1.3 with the Infra-Red Ar…
Super-Eddington Accretion in the WISE-Selected Extremely Luminous Infrared Galaxy W2246-0526
Chao-Wei Tsai, Peter Eisenhardt, Hyunsung Jun +8
We use optical and near-infrared spectroscopy to observe rest-UV emission lines and estimate the black hole mass of WISEA J224607.56-052634.9 (W2246-0526) at z = 4.601, the most lu…
Probing the High-Redshift Universe with SPICA: Toward the Epoch of Reionization and Beyond
E. Egami, S. Gallerani, R. Schneider +36
With the recent discovery of a dozen dusty star-forming galaxies and around 30 quasars at z>5 that are hyper-luminous in the infrared ( L, where $μ…
Two sub-millimetre bright protoclusters bounding the epoch of peak star-formation activity
Kevin Lacaille, Scott Chapman, Ian Smail +8
We present James Clerk Maxwell Telescope Submillimetre Common-User Bolometer Array 2 (SCUBA-2) 850 & 450 m observations ( mJy, mJy) of the HS1549+…
A machine-learning method for identifying multi-wavelength counterparts of submillimeter galaxies: training and testing using AS2UDS and ALESS
FangXia An, S. M. Stach, Ian Smail +23
We describe the application of the supervised machine-learning algorithms to identify the likely multi-wavelength counterparts to submillimeter sources detected in panoramic, singl…
An ALMA survey of CO in submillimetre galaxies: companions, triggering, and the environment in blended sources
J. L. Wardlow, J. M. Simpson, Ian Smail +15
We present ALMA observations of the mid-J 12CO emission from six single-dish selected 870-micron sources in the Extended Chandra Deep Field-South (ECDFS) and UKIDSS Ultra-Deep Surv…
The Discovery of a New Massive Molecular Gas Component Associated with the Submillimeter Galaxy SMM J02399-0136
David T. Frayer, Ronald J. Maddalena, R. J. Ivison +3
We present CO(1-0), CO(3-2), and CO(7-6) observations using the Green Bank Telescope (GBT) and the Atacama Large Millimeter Array (ALMA) of the z=2.8 sub-millimeter galaxy SMM J023…
An ALMA survey of the SCUBA-2 Cosmology Legacy Survey UKIDSS/UDS field: number counts of submillimeter galaxies
S. M. Stach, I. Smail, A. M. Swinbank +23
We report the first results of AS2UDS: an 870 m continuum survey with the Atacama Large Millimeter/Submillimeter Array (ALMA) of a total area of 50 arcmin comprising…
An ALMA survey of the SCUBA-2 Cosmology Legacy Survey UKIDSS/UDS field: Identifying candidate z~4.5 [CII] emitters
E. A. Cooke, Ian Smail, A. M. Swinbank +18
We report the results of a search for serendipitous [CII] 157.74m emitters at - using the Atacama Large Millimeter/submillimeter Array (ALMA). The search exploits…
Observational constraints on the physical nature of submillimetre source multiplicity: chance projections are common
Christopher C. Hayward, Scott C. Chapman, Charles C. Steidel +19
Interferometric observations have demonstrated that a significant fraction of single-dish submillimetre (submm) sources are blends of multiple submm galaxies (SMGs), but the nature…
A direct calibration of the IRX-β relation in Lyman-break Galaxies at z=3-5
M. P. Koprowski, K. E. K. Coppin, J. E. Geach +17
We use a sample of 4178 Lyman break galaxies (LBGs) at z = 3, 4 and 5 in the UKIRT Infrared Deep Sky Survey (UKIDSS) Ultra Deep Survey (UDS) field to investigate the relationship b…
